Using this method only because I want the epoxy to stick to the outside of the extension but not to the inside of the receiver. I think having the epoxy adhere to the extension would make for the perfect gap filler. And by leaving the very thin layer of shoe polish inside the receiver you would be able to remove the two later if desired. Extreme caution and patience would be advised in using this method. Also applying a thin layer of shoe polish to the face of the receiver and the threads on the outside of the receiver would be advised as a precaution so as not to have the epoxy stick to those areas. And when inserting the extension and barrel into the receiver wiping off the excess epoxy that would be squeezed out from between the face of the receiver and the face of the extension ring. I would do this method of installation with the receivers face in a vice pointing downward. After installing the barrel and wiping all excess epoxy away and applying some shoe polish to the threads of the outside receiver threads again and the treads of the inside of the barrel nut, tighten the two together. Not to torque specs yet because you may want to inspect the epoxy after it cures. By this I mean unscrewing the barrel nut to see if any epoxy is inside the barrel nut treads or on the outside of the receivers treads. If so it should be fairly easy to remove with a pick and brush or similar tools. That way after cleaning and greasing up the treads with Anti-sez, or some other grease,you can install and torque the barrel nut with out any obstructions between them. This might just work? Any comments welcome?
